+# Kube OpenAPI
+
+This repo is the home for Kubernetes OpenAPI discovery spec generation. The goal 
+is to support a subset of OpenAPI features to satisfy kubernetes use-cases but 
+implement that subset with little to no assumption about the structure of the 
+code or routes. Thus, there should be no kubernetes specific code in this repo. 
+
+
+There are two main parts: 
+ - A model generator that goes through .go files, find and generate model 
+definitions. 
+ - The spec generator that is responsible for dynamically generate 
+the final OpenAPI spec using web service routes or combining other 
+OpenAPI/Json specs.
